82V2052EPF

Overview

The Renesas 82V2052EPF is a dual-channel E1 short haul Line Interface Unit (LIU) designed for telecom interface applications. It operates on a single 3.3 V power supply with a voltage range of 3.13 V to 3.47 V. The device integrates an adaptive equalizer, clock and data recovery (CDR), line decoding/encoding, and one jitter attenuator. It is housed in an 80-pin TQFP package measuring 14.0 x 14.0 mm with a 0.65 mm pitch. The component supports an operating temperature range from -40°C to +85°C and has a Moisture Sensitivity Level (MSL) of 3.

Feature Summary

• Integrates adaptive equalization and clock data recovery for signal integrity
• Performs line encoding and decoding functions within a single unit
• Includes built-in jitter attenuation capabilities

Applications

• Local Area Network (LAN) infrastructure
• Wide Area Network (WAN) equipment
• Network routers and gateways
• Wireless base station systems

Procurement Notes

Verify the specific suffix 'PF' against official datasheets to confirm the exact package variant and RoHS compliance status. Check current availability as distribution channels may report limited stock or discontinuation notices. Ensure the ordering quantity aligns with manufacturer packaging constraints before finalizing procurement orders.

Selection Notes

Select this component for E1 short-haul applications requiring integrated signal conditioning. Compare pin compatibility and thermal performance against alternative LIUs if space constraints exist. Confirm that the 80-TQFP footprint matches the target PCB layout design requirements.

Part Context

This part belongs to the 82V2052 series of Line Interface Units manufactured by Renesas Electronics. It serves as a specialized interface solution for digital transmission networks, bridging digital logic levels with physical line signaling requirements for E1 standards.

Replacement Considerations

Consult official substitution guides for equivalent dual-channel E1 LIUs. Verify functional compatibility regarding equalizer settings and CDR bandwidth when considering cross-manufacturer alternatives.
